Question

Como resolver 2a(ab+b)-b (3x+a2) eliminando os parenteses

Answer 1

Greetings!

We need to Expand or Distribute the parenthesis. This by multiply the term outside the parenthesis by the numbers inside the parenthesis.

Expand

`2a(ab+b)-b (3x+a^2)`
Distribute where possible.

`2a^2b+2ab-3xb-a^2b`
Combine like terms.

`a^2b+2ab-3xb`
Rearrange.

`a^2b+2ab-3bx`

Hope this helps.
